Choosing resistors for audio circuits

[The Master]

I would like to clean up the signal as much as possible. What values do I use if I have 2 RC filters? If I calculate that I need a 10K resistor and 1uF cap for a single one then do I use 10K-1uF-10K-1uF or would it be 5K-0.5uF-5K-0.5uF for 2 of them?
